"An Audio-Visual Attention System for Online Association Learning",
INTERSPEECH, 2009.
Abstract
We present an audio-visual attention system for speech based interaction with a humanoid robot where a tutor can teach visual properties/locations (e.g "left") and corresponding, arbitrary speech labels. The acoustic signal is segmented via the attention system and speech labels are learned from a few repetitions of the label by the tutor. The attention system integrates bottom-up stimulus driven saliency calculation (delay-and-sum beamforming, a...

"Effect of endwall contouring on performance of ultra-low aspect ratio transonic turbine inlet guide vanes",
Journal of Turbomachinery, vol. 131, no. 1, pp. 011020, 2009.
Abstract
In our previous work on ultralow-aspect ratio transonic turbine inlet guide vanes (IGVs) for a small turbofan engine (Hasenjäger et al., 2005, "Three Dimensional Aerodynamic Optimization for an Ultra-Low Aspect Ratio Transonic Turbine Stator Blade," ASME Paper No. GT2005-68680), we used numerical stochastic design optimization to propose the new design concept of an extremely aft-loaded airfoil to improve the difficult-to-control aerodynamic los...

"Online Adaptation of Gaze Fixation for a Stereo-Vergence System with Foveated Vision",
International Conference on Advanced Robotics (ICAR), 2009.
Abstract
In active vision systems, which direct their gaze to different visual targets in their environment, targets are represented in image coordinates and commands by which the gaze direction is changed are represented in motor coordinates. This requires knowledge of the mapping between two coordinate frames. In this work we present a robust mechanism that learns such a mapping. The mechanism can be applied to any active vision system performing arbitr...

"A computational model for unsupervised childlike speech acquisition",
Universität Bielefeld, Technische Fakultät, 2009.
Abstract
Speech understanding requires the ability to parse spoken utterances into words. But this ability is not innate and needs to be developed by infants within the first years of their life. So far al- most all computational speech processing systems neglected this bootstrapping process. Here we propose a model for early infant speech structure acquisition implemented as layered architecture comprising phones, syllables and words. Our model processes...
